Apple Inc. is planning to release a version of its smartwatch later this year that can connect directly to cellular networks, a move designed to reduce the device’s reliance on the iPhone, people familiar with the matter said.

Currently, Apple requires its smartwatch to be connected wirelessly to an iPhone to stream music, download directions in maps, and send messages while on the go. Equipped with LTE chips, at least some new Apple Watch models, planned for release by the end of the year, will be able to conduct many tasks without an iPhone in range, the people said. For example, a user would be able to download new songs and use apps and leave their smartphone at home.
